The Activated carbon materials are known as excellent adsorbent and support a variety of environmental applications, such as purification and storage of gases. This is due to the low cost of raw materials, the availability of a wide variety of carbon sources (for example, coals, biomass, and coke pitch), the large surface area and micropore volume, and the degree of polarity. Accordingly, close attention has been drawn to the synthesis of activated carbons (AC) from waste material owing to the abundance of sources for scale-up production and environmental purposes. In this proposal, asphaltene from the PFT (Paraffinic Froth Treatment) tailings is considered as an inexpensive and readily available carbon source to synthesize novel and high surface activated carbon for different applications such as gas and water treatments, catalyst supports, and removal of heavy metals in the industry. Since current pyrolysis technologies face many challenges due to the technical complexity associated with wastes, this project will develop an innovative catalytic pyrolysis process to reduce waste disposal costs and environmental footprint with the optimum design for an industrial unit via process simulation, optimization, and techno-economic assessment providing a value-added product for the petrochemical and chemical industries. Catalytic pyrolysis of asphaltene from the PFT tailings provides consumers with a cost-effective solution to reduce waste carbon footprint in soil and provides a tool for policymakers to decarbonize the heavy oil industry significantly in Canada and the globe. An activated carbon production facility will bring to Canada outstanding capital investment through valorizing the carbon wastes. Successful completion of this study generate fundamental and practical knowledge required for the commercialized technologies that are its long-term objective. This project will provide a training opportunity for several HQP's including three Postdoctoral fellows and two Undergraduate students in the field of conversion processes.

活性炭材料被称为优秀的吸附剂，并支持各种环境应用，如气体的净化和储存。这是由于原材料成本低，碳源种类繁多（例如煤，生物质和焦炭沥青），表面积和体积大，以及极性程度。因此，由于大量的资源用于规模化生产和环境目的，从废物材料合成活性炭（AC）受到密切关注。在该提议中，来自PFT（石蜡泡沫处理）尾矿的沥青质被认为是一种廉价且容易获得的碳源，以合成用于不同应用（例如气体和水处理、催化剂载体以及工业中的重金属去除）的新型和高表面活性炭。由于目前的热解技术面临着许多挑战，由于与废物相关的技术复杂性，该项目将开发一种创新的催化热解工艺，以降低废物处理成本和环境足迹，通过工艺模拟，优化和技术经济评估为工业装置提供最佳设计，为石化和化学工业提供增值产品。PFT尾矿中沥青质的催化热解为消费者提供了一种具有成本效益的解决方案，以减少土壤中的废物碳足迹，并为政策制定者提供了一种工具，使加拿大和地球仪的重油工业大大脱碳。一个活性炭生产设施将通过对碳废物的价值评估为加拿大带来杰出的资本投资。成功完成这项研究将产生商业化技术所需的基本和实用知识，这是其长期目标。该项目将提供一个培训机会，为几个HQP的，包括三个博士后研究员和两个本科生在该领域的转换过程。
